DS' Next Top Artist Series 6: Mainstream Live Show 4!

Hello and welcome to the fourth live show of NTA6 Mainstream! Last week we unfortunately had to say goodbye to Justin Timberlake after he was beaten in the sing off by P!nk, after that the 17 remaining contestant performed their recent hits and we unfortunately had to say goodbye to Biffy Clyro and The Script!

This week the top 15 must step into the shoes of other acclaimed artists, as it's covers night! But unfortunately for two more contestants this will be the last performance they give in NTA, as we're having another double elimination tonight

Firstly, lets introduce the acts and their mentors!
